Yesterday I was losing clutch pedal. If I pumped it up several times it worked. No leaks, master is full.

Today it is working great, didn't have to pump it at all. Got in it this morning its been working ever since?????

That is the BIGGEST problem i have with life never having confidence in my first instinct! Thank you for your help. God Bless!!!!!

If the crank pulley is wobbling would that cause the engine to seem like its running rough?

It has a rough idle feels like more of a vibration i had four misfire codes mass airflow sensor code. all cylinders seem to be firing. seems to run a little smoother on a load.

Hi Steven,have you seen this problem before?Did a new distributor cure the problem?

what valve do you mean?

I have a 1996 camaro z28,with a LT1 engine. I have put 3 seals in back of the distributor shaft; it will not stop leaking. It has the distributor in the front of the engine.

Anybody ran into this problem? Do I have a bad dist. shaft?????

The noise is actually coming from the big tube coming from the back of the isc valve.Im thinking the isc is not working correctly.have one on the way,will let uall know how it works out.

I have a loud humming noise comming from the air box. Somtimes it goes away.

Sorry,i had to go out of town.I just got in this morning,it was one of the injectors in the throttle body.Thank you for all your help!Have a bless day!

The vaccum to map sensor is good,but it seems like if i have it plugged off it runs fairly better.

I have a 1989 dodge van with a 5.2,the idle surges up and down then shuts off as if it has a vaccum leak. Fuel pressure is good i smoked it for vaccum leaks found egr was leaking.I replaced it but still same problem. It smells like it is running rich, kinda burning my eyes if it runs too long. custo...

There is no sludge. The #8 cylinder only has 75lbs of compression. The rest are all over 100lbs; the spark plug is black and wet. The rest are like new.

Do you mean an injector going bad? Would that make the engine knock?

I guess I'm having piston slap, as I've been reading. I have a knocking noise until it reaches operating temp. Then the noise goes away, not all the way I can slightly hear it still.

Is there any way to determine which cylinder it is?

Sorry i have not replied,i have been out of town.The mass air flow sensor was bad on the 2001 nissan maxima.Thank you for the help,n god bless

The o2s seem to be working ok ,the rear are slow.

When engine is cold does not have any power bogs down. Fuel pump & filter has been changed. The coolant temp. sensor seems to be working okay, data on scanner seems to look good, although what should be reading from the map sensor should be?

When engine is warmed up car runs perfect.

I'm sorry i had a out of town emergency.The truck is a 1998 the door was changed no sticker under the hood.Yes it does have a crank&cam sensor It stays having spark doesnt that signal come from the cranksensor?

I dont see any other module.All the wires from the injectors go to the computer on my diagram.
